Abstract
|
|
|
Schwannomas are benign tumors arising from the myelinated nerve sheath. These tumors are generally solid, and degenerative changes can occur. However, cystic degeneration is usually noted only in parts of the tumor, and complete cystic change is rare; only a few such cases have been reported. To our knowledge, only one case of a completely cystic giant schwannoma in the lumbosacral area has been reported. Here, we report a similar case with the descriptions of the magnetic resonance imaging and pathological findings.
